.Razors, of which the following is a specification.

My invention relates to improvements in safetyrazoraand the objects of my 1mprovements are simplicity and economy iny construction and convenience and efliciency in use, particularly with referencer to holding a thin blade to the seat.

In the accompanying drawing: Figure 1 is a-face view ofl my'razor. Fig. 2 is an enlarged sectional View of the saine on the line m'of Fig. 1/, a portion of the handle being broken atv/ay. Fig. 3 is a face View of the frame on the same scale as Fig. 1, the blade and side plate being removed, and a portion of the handle broken away. Fig. 1 is a sectional View of the frame\ on the line 'y y of Fig. 3. Fig. 5 is a plan View of the blade. Fig. 6 is a plan view of the side plate. Fig. 7 is a plan view of the blank from which the frame is formed. Fig. 8 is a face view of my razor jin a modified form, a. port-ion of the handle being broken away, and Fig. 9 is an enlarged end View of the same.

The frame of my razor comprises a back or seat 10 for one broad side of the blade, a. longitudinal seat or stop 11 for the back edge of the blade, spring clamps 12 and a toothed guard 13. The blade seat 10 is provided with a projecting shoulder 14, which may be formed by making a straight slit in the metal in the line of the said shoulder and -then bending a portion of the metal toward the front, so that the said shoulder-projects from the face of the blade seat 10, as best shown in Fig. 2. An ordinary handle 15 is rigidly secured to this frame in the usual posit-ion and in any ordinary manner. The said frame is formed by cutting a blank from sheet metal of the form shown in Fig. 7, the teeth of the guard 13 being cnt frrV`v the edge of an opening or openings in the-. Qv

body of the blank, leaving the guard Vn the forni of a toothed bar, the said bar being connected with the back or body of the frame by bars 16, that are bent along the line of the ends of the teethso that the guard stands at the proper angle withfthe -which is opposite the ends of the teeth toward the blade, the /said bars in eii'ectalso constituting guard teeth the-rends of which 'are at the said bend, as shown-in Figa' 2. The longitudinal seat 11 for the back edge of the blade-is formed by turning up that edge of the blank Fig. 7, guard teeth. The springv clamps or clamping mechanism' l12 are formed by being bent over from the corresponding lugs of the blank, with their ends inclineda little -toward the blade seat 10, as shown in Fig. 4 so that their ends may seat when undertension.

The blade 17 isnierely a iiat thin piece,

Vield and exert apressure toward the blade pfith one edge sharpened and with an opening 1S near its back edge,'the said opening having a straight` edge on one side in position for engaging the shoulder 1i of the frame, to hold lthe blade against moving toward the front, while the back edge of the blade is stopped from moving in the opposite direction by the longitudinal seat or stop 11. The blade is inserted by introducing its cuttingl edge under the spring clamps from the back and carrying the blade forward until 'seated as before described. It is then held firmly to its seat by crowding in'the sliding clamp plate 19, between the broad side of the blade and the said spring'clamps from the back, unt-il the end .lugs 20 of the said plateengage the bent over portion at the junction of the said clamps with the blade seat 10, as shown in Fig. 1. The said bent over portion of the spring clamps also hold the blade against endwise displacement. l j In Figs. 8 and 9, I show the same general combination of frame, blade and clamping -slide plate, only the parts are so modiiied that the blade and slide plate must be inserted from the front instead of from the rear or back.- The blade and slide plate are precisely the same as before described and hence the same reference numerals. The frame is also provided with the same shoulder let for engaging the straight wall of the opening in the blade, a blade seat 10 for the broad .side of the blade,`spring clamps 12a, for

holdingtheslide plate, the same beinglbent4 over from the back edge of theframe and forming a longitudinal seat lola'for the back of the blade."`.The guard 13a has its teeth formedlon the outer-edge of the. blank and without the flat bai; in thefplane of the teeth that is shown in the first described construction. The frame is also provided with short; end lugs 2l to hold the blade against endwise movement and to serve as stops for the lugs of the slide plate.

In both constructions the frame is provided with spring .clamping mechanism which is put under tension by crowding the slide plate edgewise into place. ln both, the clamping mechanism holds` the broad side ofthe blade to its seat while the trame is provided with means for inerenting an edgewise' displacementl of the blade` "lhc end lugs on the slide plate servo as convenient handles, in addition to their stop function.

By my improvement the parts are `formed mainly of sheet metal. of a sii'npl'x and inexpensive construction. The blade is conveniently put, in place and when in place firmly held to its seat by a clamping plate that may be thicker than the blade which may be quite thin. The guard teeth, with the exception of those formed by the connecting bars, are straight and are in the plane of the straight llat bar that forms one edge of the frame. whereby they are less liable to injury, while the lather that passes by the said bar and teeth, readily passes through the opening or openings in the frame from which the said teeth were cnt.

l claim as my invention 1. In a safety razor, the combination of a flat thin blade, a frame comprising a bach provided with a seat for the broad side of the said blade, means for holding the said blade against edgewise displacement on the said seat, spring clamps consisting of extensions from said back to a position opposite the said blade seat and a slide plate between the said blade and clamps, whereby the said clamps are put under tension by the act of positioning the said slide plate.

- 2. In a safety razor, the combination of a Hat thin. blade, a slide plate, and a 'traine coinifirising a seat for the broad side of the blade, a pair of spring clamps at the opposite ends of the said frame, and means for holding the said blade against edgewise displacement, the said slide plate lieing forced edgewise between one broad side of the plate and said pair of clamps. y

3. In a'safety razor, the combination of a (lat thin blade,4 a frame vcomprising.; a seat for the broad side of the said blade, means for holding the said blade against edgewise displacement and spring clamps, and a slide platehaving lugs projecting from its opposite ends vwhile its body7 bet-Ween the said lugs may be forced in between the said blade and spring clamps to pnt said clamps under tension for holding the blade to its seat.

l. In a safety razor, a iiat thin blade hai'- ing an opening therethrough, a slide plate, and a frame comprising` a guard near one edge, a seat for one broad side of the said blade, a longitudinal seat at the bark of the said frame for the back edge of the blade, a shoulder projecting from the said broad seat. for being engaged by the rear wall of the opening in the said blade, means for preventing an endwise movement. of the blade on its seat, and spring clamps that may beA put under tension by forcing the said slide plate edgewise into place.
